COTTON CHCPPER AND HARRO W.

SPECIFICATION forming part of Letters Patent No. 269,716, dated December26, 1882.

Application niea June 11, 1882. (N model.)

To all 'whom it may concern:

Be it known that I, GEORGE W. ROBERTS, a citizen of the United States,and aresident of Pattonville, in the county of Lamar and State of Texas,have invented a new and valuable Improvement in Cotton Choppers andHarrows; and 1 do hereby declare that'the following is a lull, clear,and exact description of the construction and operation of the same,referto ence being bad to the annexed drawings,mak-

ing a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a plan view of my device. Fig. 2 is a sideview with the near wheel removed. Fig. 3 isacross-sectional view on lineas 00, Fig. 1. Fig.4 is a plan view,showing the barrow attached, andFig. 5 is a side view of the barrow attachment.

This invention has relation to cotton choppers and barrows; and itconsists in the construction and novel arrangement of parts, as

" will be herernafterfully described and claimed.

Referring by letter to the accom'panyingdrawings, a designates the axle,and b b the supporting-wheels. Converging and slightly curved arms 0 care let into recesses d d in the upper face of the axle a,and aresecured at their forward ends to a straight arm, 6, let into a middlereress,f,in the upper face of the axle a, as

shown in thedrawings. These three arms 0 c and e are hinged near theirjuncture, and are let into recesses g g g in the under face of a lateralbar, h, from the ends of which vertical standards i i depend, as shown.

Upon the arms 0 c and 6, between the lateral bar It and the axle a, aresecured curved racks k, and to one side of each of said arms is pivoteda hand-lever, l, engaging said racks 70. From the hand-levers lchains mextend over sheaves n, pivoted on standards 0, therear ends of saidchains at being adapted to engage the beams of the harrow orcotton-chopper sections. Referring first to the cotton-chopper sections,of which there are three, designated by the letters 1) p and p, theformer being the side sections and the latter the central one, whichlatter has two longitudinal beams, q, while the side sections have butone beam, q,

it will be seen from the drawings that these beams q q and q are hingedat their forward wardly and rearwardly to the under face of the axle, towhich they are secured by bolts or otherwise.

'lhe rear ends of the beams 11 p and p are provided with section-bars uu and a, the lat- 6o ter being the central section-bar. From thesesection bars depend forwardly -curved and pointed standards Q), threadedat their upper ends to receive securing-nuts o, and provided at theirlower ends with forwardly-inclined 6 knives to, as shown.

From the beams q of the central S80Ll0ll,1), handles w 00 extendrearwardly and upwardly, and are .bolted to standards 2 z, rising fromthe central section-bar, a, and connected near their upper ends by adouble rack, a, serrated near each end in its forward edge, theserrations pointing inwardly from said standardsz z. Braces b I) extendforward from the under face of the central section-bar, a, near each 7 5end, to the under faces of the beams q of the central SBCllOll,1)', toadd additional strength. Levers c c'are pivoted at their lower ends tothe front face of the central section-bar, u, and near the ends thereof,and extend upwardly above the double rack n and engage the serrations ofthe same.

From the levers c c, slightly below their middle portions, pivotedperforated arms d extend, and are connected by pivots e to the inner or8 forward faces of the side section-bars, u a, as shown, the object ofthe perforations in said arms being to permit a greater lateraladjustment of the bar-sections than could be acc0mplished bythe use ofthelevers cc alone when it is desired to leave larger or smallercottonstands.

Standardsf depend from the beams q q and from a cross-bar. 9, connectingthe beamsq of the central section, a, and are provided at 5 theirlowerends with wheels h, which ride over the ridges in advance of theknives and pre vent the latter from cutting too deeply, and therebyimpeding the draft of the implement.Thechains,\viththeirlevers,racks,andsheaves, 10o

permit the knives and wheels h to be elevated and permitted to remaininoperative when the implement is being transported from place to place.The chopper is to be driven across the ridges, the cotton-stands beingleft between the knives. the portions not needed being cut awaybytheknives. ln cultivating the cotton the chopper-sections are removedby detaching the cross-bar s from the standardsi 'i, and

the cross-bar i of the hinged barrow-sections k k is secured to saidstandards.

The beams l l of the lJtUIOWSPCllOllS are secured to the cross-bar i ina manner similar to the beams of the chopper-sections, and are providedwith converging tooth-bars m m and handles n n, as shown. Connectionsfor the elevating-chains are. also provided, in order that thebarrow-sections may be-rendered in-.

with the foregoing description and the accompanying drawings.

Hinged beams carrying teeth and cuttingblades and provided with leversand connecting-bars have been before used in cnltivators, cotton-choppers, &c., and are not broadly claimed herein.

Having" thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, is-

In a cotton-rhopper, the combination, with the wheeled vehicle, of theside. and central section'bars carrying the inclined knives, the handlessecured to the central section,the donbleTacl; connecting'said handles,the adjust ingdevers pivoted to the central section, and the pivotedperforated arms connecting the levers and outer section-bars,substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

GEORGE WHITFIELD ROBERTS.
